You don't have to be a metal smith to come up with a modern looking geometric bracelet.  Just metal beads and wire will do.  The tutorial is by Gloria Fort Mir over on a Spanish blog called L'Antiga Casa Sin. The pictures are pretty self explanatory if you don't want to translate the page.

The triangle version will match the one I mentioned in my past post on how to make triangular jewelry (scroll to the end).  But don't use long bugles in a bracelet application - glass beads will not hold out in an open design like this one.

I would use 24 or 26 G wire.  The instructor recommends two passes of wire to give it some rigidity. She doesn't really secure the wire ends. I would wrap the ends around the exposed wire sections. Once the wire is trimmed off, tuck the wire end down.
